Though they may appear healthy, they could be carrying dangerous bacteria.

In 2017, the CDC has investigated 10 separate multistate outbreaks of infections from people who had contact with the live poultry in backyard flocks. Between January 4 to September 22, 249 people were hospitalized and in North Carolina, one person died.

"The outbreak strains of Salmonella-infected a reported 1120 people in 48 states and the District of Columbia," the CDC writes.
